This is exactly the problem you had and which I didn't notice soon 
enough when try you to help then. Following the strict rules, well as 
always the rules are there to be broken :) and in this case too.

What you do in such case is to downgrade MVC framework to just in one 
domain object and one App, say Booking and BookingApp. In this case you 
have then only one booking open at one time and App deals with a 
workflow through that booking process, from start to end. Then you can 
open a new booking, etc.

Yes, we really need to write a guide for making GUI-like web apps in 
Aida....
